Zoltan Istvan for CA Governor

Posted by in categories: food, space, transhumanism

My free event tomorrow w/ free food in San Francisco at Stock and Trade, 4-6PM. Come here me talk transhumanism and politics, and ask questions. Network TV is on hand to film it and would love to hear from you. Free tickets are below:


The Libertarian Party of San Francisco invites you to join us as we host Zoltan Istvan in his run for governor of California. Come and discover Zoltan’s unique perspective on Libertarianism and Transhumanism, and learn how he is working to spread these ideas in California and across the nation.

Join us at Stock in Trade where you will hear Zoltan speak and have an opportunity ask questions, followed by plenty of time to socialize with other LIbertarians. We will provide appetizers and addtional food and drinks are available for purchase from the bar.

Mining asteroids mining might sound like science fiction, but it’s inching closer to reality—and it could be incredibly lucrative

Posted by in categories: energy, space

Sending a spacecraft to the far reaches of our solar system to mine asteroids might seem like an improbable ambition best left to science fiction. But it’s inching closer to reality. A NASA mission is underway to test the feasibility on a nearby asteroid, and a niche group of companies is ramping up to claim a piece of the pie.

Industry barons see a future in finding and harnessing water on asteroids for rocket fuel, which will allow astronauts and spacecrafts to stay in orbit for longer periods. Investors, including Richard Branson, China’s Tencent Holdings and the nation of Luxembourg, see a longer-term solution to replenishing materials such as iron and nickel as Earth’s natural resources are depleted.

Millions of asteroids roam our solar system. Most are thought unsuitable for mining, either because they’re too small, too inaccessible to Earth or because the materials that make up the asteroid have little value. But we know of almost 1,000 asteroids that show potential. Timing is everything, though. The varied orbits of these asteroids mean that many are nearby only once every several years.

Scientists Observe Red Giant Waking Up Neutron Star in a Flash

Posted by in categories: energy, space

Neutron stars aren’t the twinkle-twinkle kind you typically see in the night sky. They’re stellar corpses, and incredibly dense sources of gravity, with perhaps 1.5 times the mass of the sun packed into an area less than a dozen miles across. Around 9,000 light years away from Earth, one neutron star seems to have befriended a red dwarf. And scientists observed the new relationship beginning in a flash of energy.

An international team of researchers first spotted what looked like the symbiotic relationship of an old red dwarf star waking up a neutron star on August 13, 2017, using an Earth-orbiting telescope called INTEGRAL. While binary stars are common, lots of things about this finding, from capturing the initial blast that signaled the start of the stellar relationship, were a surprise.

“It was a very exciting find,” study author Arash Bahramian from Michigan State University told Gizmodo, “Especially given that it’s rare to see the start of the process.”

Should We Seed Life through the Cosmos using Laser-Driven Ships

Posted by in categories: innovation, space

Our galaxy may contain billions of habitable worlds that don’t host any life. Should we attempt to change that?Claudius Gros at the Goethe University Frankfurt, Germany, thinks we should. He believes in directed panspermia: deliberately seeding life throughout the cosmos. And to do that, he proposes we use a laser propulsion system that may not be technically out of reach.

Breakthrough Starshot is a project with ambitious aims to use such systems to send tiny, lightweight probes to Alpha Centauri. The goal is to take pictures of our nearest star, but these systems could also deliver much larger payloads into orbit around nearby stars, says Gros.

Iconic Stellar Ring Much Stranger Than Previously Thought

Posted by in category: space

You’re looking at an image of an enormous ring of debris, 237 light years away from Earth, orbiting a long-studied, young star called HR 4796A. While the bright white ring of debris may be the most visually striking part of the image, astronomers are more excited about what’s around it: the much larger, less-concentrated area of dust around it.

Scientists have long known about the dust and ring surrounding the star. The ring alone is 77 astronomical units in radius, almost twice Pluto’s average distance from our our sun. But a team recently took another look with the Hubble Space Telescope, and learned that the structure was in fact much larger and more complex than they previously thought.

“The resulting images unambiguously reveal the debris ring embedded within a much larger, morphologically complex, and biaxially asymmetric exo-ring scattering structure,” the authors wrote in the paper published recently in The Astronomical Journal. In other words, it’s big and weird-shaped. Check it out:
